8 Questions to Ask Your Doctor About Your A1C Results

Your doctor says your A1C is 6.1%. Is that good? Bad? Something to worry about? Without context, the number is almost meaningless. The conversation you have with your doctor about your A1C is just as important as the result itself. Here are eight questions that will help you walk out of that appointment genuinely informed.

1. How Does My A1C Compare to My Previous Results, and What Is the Trend?

A single A1C number is far less informative than the trend over time. An A1C of 6.1% that was 5.8% six months ago is a very different situation from 6.1% that was 6.8% six months ago. One is getting worse. The other is improving. Ask your doctor to show you the trend and explain whether the direction concerns them. If your records are scattered across different providers, consider requesting a consolidated history. The trajectory matters more than any single data point.

Why it matters for your metabolic age: your metabolic age trend mirrors your A1C trend, and both tell you whether your interventions are working.

2. Could Anything Be Making My A1C Inaccurate?

A1C measures the percentage of hemoglobin in your blood that has glucose attached to it. Anything that affects hemoglobin can skew the result. Iron deficiency anemia, sickle cell trait, recent blood transfusions, chronic kidney disease, and even certain medications can make A1C read falsely high or low. If you have any of these conditions, ask your doctor whether an alternative test, like fructosamine or glycated albumin, would give a more accurate picture of your blood sugar control.

3. What Does My A1C Translate to in Terms of Average Daily Blood Sugar?

Most people find it easier to think in terms of daily blood sugar readings rather than A1C percentages. Ask your doctor to convert your A1C to an estimated average glucose (eAG). The formula is roughly: eAG = (28.7 x A1C) - 46.7. So an A1C of 6.1% corresponds to an average blood sugar of about 128 mg/dL. This translation makes the number more tangible and helps you connect it to the readings you see on your glucometer.

Why it matters for your metabolic age: understanding your average blood sugar in daily terms helps you see how individual meals and habits connect to your broader metabolic age.

4. Is My A1C Consistent With My Home Blood Sugar Readings?

If your home glucometer shows fasting readings of 95 mg/dL every morning but your A1C suggests an average of 140 mg/dL, there is a disconnect. This could mean your post-meal blood sugar is spiking much higher than you realize, that your glucometer is inaccurate, or that your A1C is being affected by a confounding condition. Ask your doctor to help reconcile the numbers. This conversation often leads to discovering hidden post-meal spikes that home testing misses.

5. What Specific Actions Would Move My A1C by 0.5 Points?

Generic advice like “eat better and exercise more” is not helpful. Ask for specific, measurable actions tied to a specific A1C target. Your doctor might say that cutting out sugary drinks, walking 30 minutes after dinner, and losing 5% of body weight could reasonably reduce your A1C by 0.5 points in three months. Having concrete targets and a defined timeline makes follow-through more likely and makes progress measurable.

6. Should I Be Testing My Blood Sugar at Home, and If So, How Often?

Not everyone with an elevated A1C needs daily home monitoring, but many people benefit from it. Ask your doctor to recommend a specific testing schedule based on your situation. For someone with pre-diabetes, checking fasting glucose three to four times per week and post-meal glucose after their largest meal might be sufficient. For someone on medication, more frequent testing may be warranted.

Why it matters for your metabolic age: home testing gives you real-time feedback that helps you make daily decisions supporting a lower metabolic age.

7. At What A1C Level Would You Recommend Starting Medication?

Understanding your doctor’s medication threshold helps you set realistic goals. Some doctors start medication at an A1C of 6.5%, the official diabetes threshold. Others prefer to try lifestyle interventions through 7% or higher. Knowing where the line is gives you a clear target to stay above or below. It also opens a useful conversation about which medications they would consider and why.

8. How Often Should I Get My A1C Tested Going Forward?

The standard recommendation is every three months for people with diabetes and every six to twelve months for people with pre-diabetes or normal results. But your optimal testing frequency depends on your specific situation, including how quickly your numbers have been changing and whether you have recently started a new intervention. Ask your doctor to personalize the schedule so you are getting data at the intervals that are most useful for tracking your progress.
